A self-assembling surface layer flattens the cytokinetic furrow to aid cell division in an archaeon

1. Academic Background Since the origin of life, living organisms have needed to construct effective barriers to protect their cells from external physical and chemical damage. In the realms of bacteria and archaea, the surface layer (S-layer) is a universally present and exquisitely structured two-dimensional protein lattice that substitutes for t...

Intercellular Contractile Force Attenuates Chemosensitivity Through Notch-MVP-Mediated Nuclear Drug Export

Academic Background Chemotherapy resistance is one of the major challenges in cancer treatment. Traditional research has primarily focused on biochemical mechanisms (e.g., drug efflux pumps, DNA repair, etc.), but in recent years, the role of biomechanical factors in tumor progression and drug resistance has gained increasing attention. Studies hav...

Endothelial Cells Stably Infected with Recombinant Kaposi’s Sarcoma-Associated Herpesvirus Display Distinct Viscoelastic and Morphological Properties

Kaposi’s sarcoma-associated herpesvirus (KSHV) is a γ-herpesvirus that primarily infects endothelial cells and leads to the development of Kaposi’s sarcoma (KS), especially in people living with HIV. Kaposi’s sarcoma is a malignant tumor characterized by endothelial cell proliferation, typically presenting as cutaneous lesions. After infecting endo...
